8 animals with an extreme sex life

When it comes to sex, humans like to think we've got it
covered. From Mile High clubs to swingers parties, BDSM to dinosaur erotica – there isn't a kink that as a species we haven’t consentingly explored.
But when it comes to extreme copulation techniques, humans still take second
place to these next-level copulators.

Like the gentle, graceful and elegant giraffe who, in lieu
of a diary that keeps
track of ovulation dates, engages in some friendly water sports. To check
fertility, male giraffes will respectfully take a sip of the female's urine in what's known as the flehmen response, or a seductive
curling up of the lip and nostrils. (badjonni/Flickr)
